2.若用C語言,還有另外一個寫法,使用_itoa(),Microsoft將這個function擴充成好幾個版本,可參考MSDN Library。 1 /* 2 (C) OOMusou 2007http://oomusou.cnblogs.com 3 4 Filename : int2str_itoa.cpp 5 Compiler : Visual C++ 8.0 / ANSI C 6 Description : Demo the how to convert int to const cha...

std::string为library type,而int、double为built-in type,两者无法互转,这里使用function template的方式将int转std::string,将double转std:string。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : ArrayToVectorByConstructor.cpp ...
The to_string function converts the integer value to a string. main.rs fn main() { let val = 4; let s1 = String::from("There are "); let s2 = String::from(" hawks"); let msg = s1 + &val.to_string() + &s2; println!("{}", msg) } ...
The itoa() function coverts the integer n into a character string. The string is placed in the buffer passed, which must be large enough to hold the output. The radix values can be OCTAL, DECIMAL, or HEX. When the radix is DECIMAL, itoa() produces the same result as the following st...
